I recently cleanly installed Manjaro 25 on my laptop, dual-booting with MX Linux 25 (for some Debian stability).

I have a near-perfect setup now for my liking. The only thing not working is the timeshift-autosnap.

Can anyone please help me solve this problem?

Please provide system information as described (below). I’m sure someone will help when they are able.

Regards.


What follows is from a standard template.

Welcome to the Manjaro community

As a new or infrequent forum user, please take some time to familiarise yourself with forum requirements, and the many ways to use the forum to your benefit.

Note: By virtue of using the Manjaro forum you acknowledge and agree to follow Rules and Guidelines outlined; so, you really should read them:

Required Reading
Highly Recommended

Work with us, not against us

It is important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem. Please also be prepared to provide output from commands if/when asked.

Simply waiting for others to ask you questions is counter-productive – typically, nobody has a :crystal_ball: at their disposal – and your clear, concise and accurate input is often relied upon in order to help you.

Please help others to make informed suggestions based on information you provide.


System Information

While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; :eyes:

Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:

Suggested inxi command (use either):

inxi -zv8 (short-form)
inxi --filter --verbosity=8 (long-form)
inxi man pages (manual)
If running `inxi` within a `chroot` environment
  • Add --color=0 to the long-form command, or…
  • Change the short-form command to inxi -zv8c0

The problem was with how I created my swapfile. I recreated the swapfile following the guidelines from the Arch wiki.

The /swapfile can not be snapshotted. So needed a /swap subvolume first.

I put the swapfile in /swap/swapfile.

Then edited the /etc/fstab and followed the Arch wiki on Btrfs again.

This solved the problem, and now I get the following.
